ETHYMONICS FREE MUSIC LICENSE
Version 1, August 2000
Copyright (C) 2000, Ethymonics Limited
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
The licenses for most musical works are designed to take away your
freedom to share the music. By contrast, this Free Music License is
intended to guarantee your freedom to make copies of a piece of music,
and charge for this service if you wish. Recipients of those copies
have the same freedom. The word "Free" in "Free Music License" means
the freedom to make copies. It does not mean that those copies cannot
then be sold.
This license is designed to protect and pass on the right to make
copies to whoever receives a copy. This encourages wide distribution on
the artist's behalf. You can apply this license to your own music too.
To protect the right to copy the music, it is necessary to pass on
certain requirements that must be followed when the music is copied or
distributed. For example, if you distribute a piece of music subject to
this license, even if this is done for a fee, you must give the
recipients all the rights that you have. You must show them these terms
so that they know their rights.
The freedom to copy is protected by two things: (1) Copyright of the
music, and (2) This license that provides legal permission to copy and
distribute the music.
The precise terms and conditions for copying, distribution and
FREE MUSIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND PERFORMANCE
1. This License applies to any musical work or other type of work which
has a notice placed by the copyright holder saying that it may be
distributed under the terms of this Free Music License. The "Music",
below, refers to any such music or work, whether in a recording,
performance or other form of musical representation, or any derivative
work under copyright law: that is to say, a work, in any medium,
containing the Music or a portion of it, either unaltered, modified and
You may play or perform the Music publicly, for example in a broadcast,
provided that you make available to listeners the title of the work and
the name of the Artist. A recording made as a result of the Music being
played or performed is covered by this License when its contents
constitute a work based on the Music. If a listener wishes to make
copies of such a recording, the terms and conditions of this License
must be made available to them, along with any other information
required to make and distribute copies according to the terms and
conditions of this License.
2. You may copy and distribute copies of the Music as you receive it,
in any medium, provided that you:
(a) conspicuously and appropriately publish on each copy an appropriate
(b) keep intact all the notices that refer to this License;
(c) supply, with each copy of the Music, all significant information
about the Music, including the title of the work, the name of the
artist, and the names and roles of all credited personnel;
(d) supply, to each recipient of the Music, along with the Music,
either a copy of this License or a clearly visible URL that lets the
recipient know where to find a copy of this License on the Internet.
If the information required by (a) to (d) above is not available, for
example when the Music has been received by making a recording of a
performance, then this information must be obtained independently and
no copies can be made or distributed without this information being
included with each copy of the Music.
You may, at your option, charge a fee for the act of supplying a copy
of the Music.
3. You may not copy, distribute, perform or sub-license the Music
except as expressly provided under this License. Any attempt to
otherwise do so is void, and will automatically terminate your rights
under this License. However, parties who have received copies, or
rights, from you under this License will not have their Licenses
terminated as long as such parties remain in full compliance.
4. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to copy,
distribute, play or perform the Music or any of its derivative works.
Therefore, by copying, distributing, playing or performing the Music,
or any of its derivative works, you indicate your acceptance of this
License to do so, and all of its terms and conditions.
5. Each time you redistribute the Music the recipient automatically
receives a license from the original licensor to copy, distribute, play
and or perform the Music subject to the terms and conditions of this
License. You may not impose any further restrictions on the recipient's
exercise of the rights granted herein. You are not responsible for
enforcing compliance by third parties to this License.
6. If, as a consequence of a court judgment or allegation of copyright
infringement or for any reason (not limited to copyright issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot satisfy
simultaneously your obligations under this License and any other
pertinent obligations, then your rights under this License are
terminated. For example, if an existing agreement would not permit
royalty-free redistribution of the Music by all those who receive
copies directly or indirectly through you, then the only way to satisfy
both it and this License would be to refrain entirely from
redistributing the Music.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
It is not the purpose of this section to induce you to infringe any
copyright or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of a music distribution system, which is implemented by
copyright and license practices.
7. If an activity permitted by this License is restricted in certain
countries either for copyright or other reasons, the original copyright
holder who places the Music under this License may add an explicit
geographical distribution limitation excluding those countries, so that
distribution is permitted only in or among countries not thus excluded.
In such cases, this License incorporates the limitation as if written
in the body of this License.
8. Ethymonics may publish revised and or new versions of the Free Music
License from time to time. Such new versions will be similar in spirit
to the present version, but may differ in detail to address new
problems as they arise.
Each License is given a distinguishing version number. If the Music
specifies a version number of this License which applies to it, and
"any later version", you have the option of following the terms and
conditions either of that version or any later version published by
Ethymonics. If the Music does not specify a version number of this
License, you may choose any version ever published by Ethymonics.
9. If you wish to incorporate parts of the Music into another work
whose distribution conditions are different, write to the composer to
ask for permission.
